Before the tx path rework, ath_tx_fill_desc was called for either one aggregate, or one single frame, with the length of the packet or the aggregate as a parameter. After the rework, ath_tx_sched_aggr can pass a burst of single frames to ath_tx_fill_desc and sets len=0. Fix broken duration calculation by overriding the length in ath_tx_fill_desc before passing it to ath_buf_set_rate.

Problem now is that it then requires also CAP_NET_RAW when calling into hci_sock_sendmsg. This is not intended and just an oversight since general HCI sockets (which do not require special permission to bind) and HCI User Channel share the same code path here. Remove the extra CAP_NET_RAW check for HCI User Channel write operation since the permission check has already been enforced when binding the socket. This also makes it possible to open HCI User Channel from a privileged process and then hand the file descriptor to an unprivilged process.
